Abstract

L'invention concerne également un procédé de traitement de matière cellulosique fibreuse à partir d'algues comprenant les étapes consistant à : (I) mettre en suspension la matière cellulosique fibreuse dans de l'eau pour former une suspension ; et (ii) faire passer la suspension à travers au moins une chambre présentant une lacune importante, à un cisaillement élevé pour produire des nanofibrilles de cellulose. L'invention concerne également des nanofibrilles de cellulose et des nanocristaux de cellulose, des produits, des procédés et des utilisations de ceux-ci.
